Reasoning or why should it be changed/implemented?

Media Files are not uploaded to te server

Environment data

iOS version: iOS 18.6

Nextcloud iOS app version: 7.1.1.0

Server operating system: Debian

Web server: nginx

Database: PostgreSQL 17

PHP version: 8.2

Nextcloud version: 31.0.8

Start by reproducing automatic upload with an image taken or received through WhatsApp on iOS 18.6, then inspect the upload logs around “Asset not found” and the DAV 404 responses. Done means the affected media files are uploaded successfully instead of remaining in the activity list as failures.
